Adaptive systems on a chip (aSoC) for low-power signal processing

Adaptive system-on-a-chip, aSoC, is an on-chip communications architecture designed to promote scalability and flexibility in system-on-a-chip designs. This paper describes the use of aSoC to allow for dynamic power management of video signal processing systems. Content variation and perceptual tolerance in video signals can be exploited to trade quality for low power gracefully. The regularity and flexibility of the aSoC architecture provides a predictable framework for modeling the power, speed and area requirements of global communications that dominate configurable video processing.
